How to run a simple Whisper (SHH) example

Question

I am struggling to get a simple whisper (shh) example running. I am using the following versions: geth 1.9.24-stable-cc05b050 web3 6.14.5

I am running geth with the following command:

geth --shh --rpc

And I start coding with the following linex:

var Web3 = require('web3');
var web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));
var shh = web3.shh;
(async function main() {
   var keyPair = await shh.newKeyPair();
})();

Then I get the following error:

Error: Returned error: the method shh_newKeyPair does not exist/is not available

I guess that the shh command is not supported by the node (geth).

Can anyone instruct how to get a simple message passing example using Whisper running with the versions above? Thanks for the support.

v1.9.24 no longer has whisper, it has been trashed since v1.9.21. You should use a previous version. (like v1.9.17)
